Review Meta Analysis
The predictive value of KRAS, NRAS, BRAF, PIK3CA and PTEN for anti-EGFR treatment in metastatic colorectal cancer: A systematic review and meta-analysis.
In metastatic colorectal cancer, mutation testing for KRAS exon 2 is widely implemented to select patients with wild-type tumors for treatment with the monocloncal anti-EGFR antibodies cetuximab and panitumumab. The added predictive value of additional biomarkers in the RAS-RAF-MAPK and PI3K-AKT-mTOR pathways in colorectal cancer is uncertain, which led us to systematically review the impact of alterations in KRAS (outside of exon 2), NRAS, BRAF, PIK3CA and PTEN in relation to the clinical benefit from anti-EGFR treatment. ⋯ Meta-analysis suggests that mutations in KRAS exons 3 and 4, NRAS, BRAF and PIK3CA and non-functional PTEN predict resistance to anti-EGFR therapies and demonstrates that biomarker analysis beyond KRAS exon 2 should be implemented for prediction of clinical benefit from anti-EGFR antibodies in metastatic colorectal cancer.

Review
Non-steroidal anti-inflammatory treatment in cancer cachexia: a systematic literature review.
There are no established treatments for cachexia. Recently it has been suggested that the evidence for non-steroidal anti-inflammatory (NSAID) treatment is sufficient to support its regular clinical use. Primary objective in this systematic review was to assess efficacy and safety of NSAID treatment in improving body weight and muscle mass in patients with cancer cachexia. Secondary objectives were to assess whether this treatment could improve other cachexia domains such as anorexia and food intake, catabolic drive and function. ⋯ NSAIDs may improve weight in cancer patients with cachexia, and there is some evidence on effect on physical performance, self-reported quality of life and inflammatory parameters. Evidence is too frail to recommend NSAID for cachexia outside clinical trials. This is supported by the known side effects of NSAIDs, even though the reviewed literature report almost negligible toxicity.

Review Meta Analysis
Interventions for alleviating cancer-related dyspnea: a systematic review and meta-analysis.
Dyspnea is commonly encountered by many cancer patients in the terminal stage of their disease and it severely hampers their quality of life. We aimed to evaluate the role of interventions to alleviate dyspnea. ⋯ Our systematic review and meta-analysis demonstrate a beneficial effect to opioids in alleviating cancer-related dyspnea, and no advantage for the use of oxygen.
